A big tractor becomes a fuel-hog when used at low power. That because an engine only runs efficently within a certain load-range. A 140 horse tractor used to do a 20 horsepower job will use more fuel than an old 8N Ford gas tractor. That's why tractors need to be sized for the work they do to be efficient.
For example, a Deere 7220 with a 414 turbo-diesel when worked at 104 horsepower has an efficiency rating of 18 horsepower hours per gallon. When worked at 44 horsepower efficiency drops to 11. When worked at 22 horsepower efficiency drops to 7 horsepower hours per gallon. And old Ford 8N with a flathead gas engine when worked at 22 horsepower has an efficiency of 9.6 horsepower hours per gallon - beating the modern Deere diesel.
